This could be an interesting development.
New Rotary Engine From Austro
Diamond Aircraft's Austro Engines has bench tested a new dual FADEC-controlled rotary aircraft engine, the AE80R, that aims to match a weight of 60 pounds with a power output of 80 hp. The engine has been in development for more than two years and builds on Austro's experience with the AE50R 55-hp rotary engine but has differences in its internal design that incorporates a "no loss lubrication system." The new engine is targeting the LSA and ultralight aircraft markets, and may also see use in unmanned aircraft. Austro Christian Dries, chairman and owner of Diamond Aircraft, which owns Austro, says the new engine "has no vibration" and is a good fit for weight-sensitive small aircraft.
According to Diamond, the dual FADEC system will keep fuel consumption at its lowest possible limits and the engine oil system will result in extremely low oil consumption, maximizing its efficiency. Austro Engine last summer pursued airframe manufacturers other than Diamond, seeking potential matches for its diesel engines, which it sees as a growing segment in European aircraft markets. The company already offers diesel and rotary style engines. Austro's recent production of AE50-series rotary engines has been close to 125 engines per year.

One of the drawbacks is that the engine calls for 100LL,

According to the tech sheet on the Austro Engine website, the 55 hp version already in production permits 100LL or 95 RON unleaded, which is equivalent to most hi-octane unleaded in the US.

If the Aircraft Rotary engine is anything like the Mazda Rotary engine then this will be a great engine, perhaps better than the Rotax. I used to have a Mazda RX3, it was great! The power to weight was superb!

Re the Rotary engine,
I ran a Ro80 with a Wankel Rotary for a couple of years. Ultra smooth and it
would run on almost any grade of fuel I liked it very much.
However I hope things have improved technically. Fuel consumption was high,
around 22 mpg when a similar car would have been 32 mph. Starting problems
became a major set back and the oil consumption was unbelievable.
I visited a local Air and Transport Museum a few years agoI was surprised to
find my old car on display.
Cheers
Pat
